CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a U.S. National Phase Application under 35 U.S.C.371 of International Application No. PCT/EP2021/076381, filed on Sep.24, 2021, which claims the benefit of European Patent Application No.20198094.3, filed on Sep. 24, 2020. The entire disclosure of the aboveEuropean Patent Application is incorporated herein by reference.

FIELD

The present disclosure relates to antiwear films and a method forproducing antiwear films, as well as decorative panels comprising anantiwear film and a method for producing decorative panels comprising anantiwear film.

BACKGROUND

This section provides background information related to the presentdisclosure which is not necessarily prior art.

Decorative panels comprising an antiwear layer are known per se and areused in particular as panels for decorative cladding of floors, walls,ceilings or doors. In the sense of the disclosure, the term decorativepanel is understood to mean wall, ceiling, door or floor panels whichhave a decoration applied to a carrier plate. Decorative panels are usedin a variety of ways, both in the field of interior design of rooms andfor the decorative cladding of buildings, for example in exhibitionstand construction. One of the most common fields of application ofdecorative panels is their use as floor covering and for coveringceilings, walls or doors. In many cases, the decorative panels comprisea decoration and a surface structuring that is intended to imitate anatural material.

For protecting the applied decorative layer, wear protection or coverlayers are usually applied above the decorative layer. In many cases, itis provided that a surface structuring imitating a decorative templateis incorporated into such wear protection or cover layers, so that thesurface of the decorative panel has a haptically perceptible structure,the shape and pattern of which are adapted to the decoration applied, inorder to achieve a reproduction of a natural material as faithful aspossible even with respect to the haptic.

As antiwear layers for decorative panels, in particular layers made ofthermosetting plastics, such as melamine resins, have established. Adisadvantage of such antiwear layers can be that they impair therecyclability of decorative panels, especially when applied thereon.Furthermore, layers of thermosetting plastics can only be produced withdifficulty as semi-finished products, which results in limitations inprocess control during the manufacture of decorative panels withantiwear layers.

Antiwear layers for decorative panels and their production can thereforestill offer potential for improvement.

SUMMARY

This section provides a general summary of the disclosure, and is not acomprehensive disclosure of its full scope or all of its features.

It is therefore the object of the present disclosure to provide improvedantiwear layers which allow a more flexible process control in theproduction of decorative panels with wear protection and improvedrecyclability of such panels.

The disclosure proposes an antiwear film. The antiwear film comprises athermoplastic carrier film and an antiwear layer arranged on thethermoplastic carrier film, wherein between the thermoplastic carrierfilm and the antiwear layer an adhesion promoter layer is arrangedpartially, wherein said thermoplastic carrier film comprises athermoplastic resin, said adhesion promoter layer comprises an adhesionpromoter, and said antiwear layer comprises a mixture including apolymethyl methacrylate and polyorganosiloxane.

Surprisingly, it has been shown that good wear protection properties ofdecorative panels can be achieved by the antiwear film described above.Compared to known antiwear layers, the antiwear film according to thedisclosure can be advantageously produced as a semi-finished product,which results in a more flexible process control during the productionof decorative panels. In addition, it has been surprisingly found, thatthe antiwear film has an improved recyclability in combination withdecorative panels. At the same time, no impairments are apparent withregard to the appearance of decorative panels provided with the antiwearfilm according to the disclosure.

In the sense of the disclosure, the term “antiwear film” is to beunderstood as a film which can be applied to decorative panels or othermaterials and which protects against wear, in particular againstphysical impact. Accordingly, the term “antiwear layer” is to beunderstood in the sense of the disclosure as a layer which protectsagainst wear.

In the sense of the present disclosure, the term “thermoplastic resins”is understood to mean plastics, each of which can be plasticallydeformed within a certain temperature range. For example, polyvinylchloride, polyolefins, such as polyethylene (PE) or polypropylene (PP),polyamides (PA), polyurethanes (PU), polystyrene (PS), acrylonitrilebutadiene styrene (ABS), polymethyl methacrylate (PMMA), polycarbonate(PC), polyethylene terephthalate (PET), polyether ether ketone (PEEK) ormixtures or copolymers thereof can be thermoplastic resins.

In the sense of the present disclosure, an “adhesion promoter” isunderstood to mean a substance suitable for producing a better bondbetween two materials, in particular the adhesion between the carrierfilm and the antiwear layer.

Accordingly, an antiwear film as described above can in particularenable a better recyclability of decorative panels provided therewithand a more flexible process control during their manufacture.

In detail, the antiwear film according to the disclosure comprises athermoplastic carrier film. The carrier film comprises a thermoplasticresin. The carrier film thus advantageously serves as a carrier forfurther layers of the antiwear film and can, in particular, preventthese from tearing unintentionally. The carrier film can also serve as abonding layer in a subsequent production of a decorative panel. Inaddition, the carrier film can allow easy handling of the antiwear film.For example, the antiwear film may be coilable by means of the carrierfilm, which may allow for easy storage of the antiwear film. Thethermoplastic properties of the carrier film can also prevent stressesin a decorative panel comprising an antiwear film according to thedisclosure, since the thermoplastic carrier film can at least partiallyadapt to unevenness or tensile stresses during manufacture.

According to the disclosure, an antiwear layer is arranged on thethermoplastic carrier film. The antiwear layer comprises a mixturecomprising a polymethyl methacrylate and a polyorganosiloxane.Surprisingly, it could be shown that good wear protection properties canbe achieved by the mixture comprising polymethyl methacrylate andpolyorganosiloxane. Without being bound to theory, it is assumed thatthe polyorganosiloxane in the antiwear layer migrates to the surface ofthe antiwear film, where it forms an area with high scratch resistancethat cannot be wiped off.

The antiwear film moreover comprises an adhesion promoter layer, whereinthe adhesion promoter layer includes an adhesion promoter. Surprisingly,it could be shown that such an adhesion promoter layer does not impairthe wear protection properties of the antiwear layer and, at the sametime, the adhesion between the antiwear layer and the thermoplasticcarrier film is improved. In this way, it is possible to ensure that theantiwear layer is not unintentionally detached from the thermoplasticcarrier film when stressed, which would severely impair the wearprotection properties. In particular, it can be achieved that theantiwear layer does not detach from the thermoplastic carrier film, forexample, when the antiwear film is coiled up and stored for a long timeor during further processing of the antiwear film.

Surprisingly, it could also be shown that the antiwear film can beeasily recycled as a whole without the need for mechanical separation ofthe individual layers. Thus, the interaction of the various layers as awhole results in the advantageous properties of the antiwear filmaccording to the disclosure.

Preferably, it can be provided that the thermoplastic carrier filmcomprises greater than or equal to 75 wt.-%, more preferably greaterthan or equal to 90 wt.-%, further preferably greater than or equal to95 wt.-%, particularly preferably greater than or equal to 99 wt.-%,based on the thermoplastic carrier film of the thermoplastic resin.

This means that the thermoplastic carrier film may also comprise othersubstances in addition to the thermoplastic resin, but consistsessentially of the thermoplastic resin. For example, the thermoplasticcarrier film may include additives which, for example, affect the color,the impact strength or the flammability of the carrier film. It has beenshown that in the indicated ranges, the advantageous recyclingproperties and carrier properties of the thermoplastic carrier film areparticularly well pronounced. In particular, however, the use of thestructure according to the disclosure results in a decorative panelwhich is particularly advantageously recyclable as a whole.

This is understood to mean that the adhesion promoter layer consistsessentially of adhesion promoter, but may also comprise othersubstances. For example, it may be provided that the adhesion promoteris diluted with or dispersed in a plastic. In this way, it can beachieved, for example, that the adhesion promoter is readily processableduring the production of the antiwear film and can be applied simply andthin onto the thermoplastic carrier film. In the aforementioned ranges,the advantages achieved by the adhesion promoter layer are particularlypronounced.

Preferably, it can be provided that the antiwear layer comprises greaterthan or equal to 75 wt.-%, more preferably greater than or equal to 90wt.-%, further preferably greater than or equal to 95 wt.-%,particularly preferably greater than or equal to 99 wt.-%, based on theantiwear layer of the mixture comprising polymethyl methacrylate andpolyorganosiloxane.

This means that the antiwear layer in addition to polymethylmethacrylate and polyorganosiloxane may comprise other substances, butessentially consists of polymethyl methacrylate and polyorganosiloxane.It could be shown that in the range other substances can be added to theantiwear layer which, for example, advantageously change the impactstrength, the flammability or the optical properties of the antiwearlayer. In the aforementioned ranges the antiwear layer exhibitsparticularly good wear protection properties.

By use of the aforementioned thermoplastic resins, it can be achievedthat the antiwear film is particularly well recyclable. In addition, itcan be achieved that the antiwear film is particularly stable.Surprisingly, it has been shown that the aforementioned thermoplasticresins are adapted to make the thermoplastic carrier film particularlythin without impairing the mechanical properties of the antiwear filmtoo much. Without being bound by theory, it is assumed that thesethermoplastic resins, and in particular polypropylene, are particularlycompatible with the composition of the antiwear layer.

This allows to achieve particularly strong adhesion between the antiwearlayer and the thermoplastic carrier film. Surprisingly, it could beshown that in particular maleic anhydride-modified polypropylene graftcopolymer is particularly suitable for improving the adhesion, even ifthe antiwear layer includes a high proportion of polyorganosiloxane.

Preferably, it may be provided that the maleic anhydride-modifiedpolypropylene graft copolymer has a maleic acid content in a range fromgreater than or equal to 0.1 wt.-% to less than or equal to 5 wt.-%,preferably from greater than or equal to 0.5 wt.-% to less than or equalto 1.5 wt.-%, based on the maleic anhydride-modified polypropylene graftcopolymer.

Accordingto a further preferred embodiment, the impact strength modifier is atleast one compound selected from the group consisting of thermoplasticelastomers, ethylene glycol dimethacrylate, ethylene butyl acrylate,ethylene-methyl acrylate copolymer and polybutyl acrylate.

Surprisingly, it could be shown that in this way the impact strength ofthe antiwear layer could be improved without deteriorating the wearproperties, such as the scratch resistance.

Preferably, it may be provided that the polyorganosiloxane is apolydimethylsiloxane.

Polydimethylsiloxane can be dissolved particularly well in polymethylmethacrylate compared to other polyorganosiloxanes. As a result, aparticularly stable antiwear layer can be achieved. Furthermore,polydimethylsiloxane advantageously has a particularly little adverseeffect on the optical properties of the antiwear layer.

In other words,the number average molecular weight indicates the expected molar mass ofa polymer molecule taken at random from the sample.

It has been shown that polyorganosiloxanes with the indicated molecularweight are particularly suitable for producing an antiwear layer withparticularly good antiwear properties.

It may be particularly preferred that the polyorganosiloxane ispolydimethylsiloxane with a number average molecular weight in a rangefrom greater than or equal to 100 kDa to less than or equal to 300 kDa.

In this way, particularly advantageous wear properties can be achievedand, at the same time, a particularly high transparency of the antiwearlayer can be maintained.

Preferably it may be provided that the mixture comprising polymethylmethacrylate and polyorganosiloxane comprises polymethyl methacrylate ina range of greater than or equal to 90 wt.-% to less than 100 wt.-%,preferably greater than or equal to 95 wt.-% to less than or equal to99.9 wt.-%, further preferably greater than or equal to 98 wt.-% to lessthan or equal to 99.5 wt.-%, particularly preferably greater than orequal to 98.5 wt.-% to less than or equal to 99 wt.-%, based on themixture, wherein the mixture comprising polymethyl methacrylate andpolyorganosiloxane comprises polyorganosiloxane in a range from greaterthan 0 wt.-% to less than or equal to 10 wt.-%, preferably greater thanor equal to 0.1 wt.-% to less than or equal to 5 wt.-%, furtherpreferably greater than or equal to 0.5 wt.-% to less than or equal to 2wt.-%, particularly preferably greater than or equal to 1 wt.-% to lessthan or equal to 1.5 wt.-%, based on the mixture.

In the ranges indicated, good wear properties can be advantageouslyachieved and, at the same time, a good processability of the antiwearlayer and a good adhesion to the thermoplastic carrier film can bemaintained.

In this way, it can be achieved that the carrier film has a particularlygood stability. In this way it can particular be achieved that thethermoplastic carrier film tears only poorly during further processingor when coiled up for storage. In addition, it can be achieved in thisway that the carrier film has a sufficient thickness to compensate forstresses between the panel and the antiwear layer when used in adecorative panel.

Preferably, it may be provided that the adhesion promoter layer has athickness in a range from greater than or equal to 1 μm to less than orequal to 0.1 mm.

In this way, a particularly good adhesion can be achieved

In particular, it may be advantageouslyprovided that the thickness of the antiwear layer is greater than orequal to 5% to less than or equal to 30% of the total thickness of thefilm structure according to the disclosure consisting of an antiwearlayer, an adhesion promoter layer and a carrier film.

In this way, it can be achieved that the polyorganosiloxane forms alayer with a particularly advantageous thickness at the surface of theantiwear film. Thus, a particularly good and, in particular, durablewear protection can be achieved.

Preferably, it can be provided that the antiwear film has a web-likeshape.

In the sense of the present disclosure, a “web-like shape” can beunderstood to mean a shape which has a significantly greater widthcompared to its thickness and a significantly greater length compared toits width, for example greater than 15 meters.

In this way the antiwear film can be used particularly well for theproduction of decorative panels. In particular, the antiwear film canthus be easily coiled up and stored on reels and used at a later timefor the production of decorative panels. In addition, a web-like shapecan be produced continuously. Accordingly, an antiwear film with aweb-like shape can be produced correspondingly simultaneously with othercomponents of a decorative panel and can easily be continuously broughttogether with these components, for example, via rolls.

Preferably, it can be provided that the antiwear layer at leastpartially has a surface structuring.

Advantageously, in this way a pleasant haptic impression of the surfaceof the antiwear film can be provided.

In this way it can advantageously be achieved that the wear protectionproperties can be further improved. Compared to antiwear layers thatonly have a lacquer-containing top layer and do not have an antiwearlayer comprising polymethyl methacrylate and polyorganosiloxane, such afurther improvement of the wear protection wear protection propertiescan even be achieved with a particularly thin lacquer-containing toplayer, wherein the recyclability is deteriorated only to very littleextent.

By arranging the decorative layer on the carrier plate, the decorativepanel can be produced particularly easily by known means.Advantageously, it can be achieved that the decoration can be appliedparticularly precisely, because the carrier plate has a certainstability, which facilitates precise application of the decoration. Byapplying the decorative layer onto the thermoplastic carrier film, itcan be achieved that the decoration can be aligned particularlyprecisely with a structuring of the antiwear layer. A first decorativelayer on the carrier plate and a second decorative layer on the carrierfilm advantageously allow depth effects to be realized in thedecoration.

In other words, it may be provided that the decorative layer contactsthe carrier plate and the laminating adhesive layer is disposed on thedecorative layer, wherein the thermoplastic carrier film is disposed onthe laminating adhesive layer.

In this context, a layered silicate powder is understood to mean, in amanner known per se, a powder of a layered silicate. A layered silicateis a known term for minerals from the group of silicates, the silicateanions of which are usually arranged in layers. For example, layeredsilicates are understood to mean minerals from the mica group, thechlorite group, the kaolinite group and the serpentine group.

Thus, the solid material is advantageously formed at least by a majorpart from the mineral substance layered silicate, wherein this substancecan be used, for example, in powder form or can be present in thecarrier plate in the form of particles. In principle, the solid materialcan consist of a powdery solid.

Particularly when using layered silicate powder with particles, thecarrier plate or the decorative panel exhibits particularly preferredmechanical properties. For the determination of the particle sizedistribution, recourse can be made to the generally known methods, suchas laser diffractometry, by means of which particle sizes in the rangefrom a few nanometers to several millimeters can be determined. By meansof this method, it is also possible to determine D₅₀ or D₉₈ values whichrespectively indicate that 50% (D₅₀) or 98% (D₉₈) of the measuredparticles are smaller than the respective specified value. The sameapplies to the determination of the grain size or the mean grain size.These values, too, can preferably be determined by means of laserdiffractometry.

In the case of a discrepancy between the measured values obtained bydifferent measuring methods, the value determined by means of laserdiffractometry is considered by the applicant to be representative.

Furthermore, it may be advantageous if the first layered silicate powderis present at a bulk density according to DIN 53468 in a range from ≥2.4g/cm³ to ≤3.6 g/cm³, such as in a range from ≥2.9 g/cm³ to ≤3.1 g/cm³.Furthermore, it may be advantageous if the second layered silicatepowder is present at a bulk density according to DIN 53468 in a rangefrom ≥3.4 g/cm³ to ≤4.6 g/cm³, such as in a range from ≥3.9 g/cm³ to≤4.1 g/cm³.

Further preferably, it can be provided that the antiwear layer at leastpartially has a surface structuring and the surface structuring is atleast partially synchronous with a decoration of the decorative layer.

This allows the decorative panel to imitate a template materialparticularly well.

The disclosure further proposes a method of producing the antiwear filmaccording to the disclosure. In the method, a thermoplastic resin iscoextruded, extrusion-coated and/or laminated, preferably coextrudedinto a thermoplastic carrier film, an adhesion promoter into an adhesionpromoter layer, and a mixture comprising polymethyl methacrylate andpolyorganosiloxane into an antiwear layer while forming the antiwearfilm.

Coextrusion in particular means that the thermoplastic resin iscoextruded into the thermoplastic carrier film, the adhesion promoterinto the adhesion promoter layer and the mixture comprising polymethylmethacrylate and polyorganosiloxane into the antiwear layer whileforming the antiwear film. This means that the thermoplastic resin, theadhesion promoter and the mixture comprising polymethyl methacrylate andpolyorganosiloxane are respectively extruded by an extruder and aredirectly brought together, whereby the antiwear film is directlyobtained.

Advantageously, the antiwear film according to the disclosure can beproduced particularly well by the method described above.

In this embodiment, it may preferably be provided that the thermoplasticcarrier film is produced in the first step, the adhesion promoter layeris extruded onto the thermoplastic carrier film in the second step, andthe antiwear layer is extruded onto the adhesion promoter layer in thethird step.

Laminating in particular means that the layers are all producedindividually and are bonded together in a separate step.

It may be provided that processes are combined with each other. Forexample, it may be provided that the thermoplastic carrier film isproduced in a first step and the adhesion promoter layer is extrudedthereon in a second step. In a third step, for example, the antiwearlayer can be extruded separately and then laminated onto the layercomposite of thermoplastic carrier film and adhesion promoter layer.Alternatively, for example, the thermoplastic carrier film and theadhesion promoter layer can be coextruded.
